Small enough to hold in the palm of your hand, the C15 was more than capable of producing a satisfying, full range sound. Incorporating a new 110mm (5.25 inch) polymer cone bass/midrange unit and 19mm (0.75 inch) metal dome tweeter, as KEF’s entry level miniature speaker it had a heritage extending back to the celebrated Cresta of the 1960s.

C25 (1988-91)

KEF had been at the forefront in eliciting superb sound from tiny loudspeakers since the days of the first ‘mini-monitor’. The C25 was a new expression of this great tradition. Bass was provided by KEF’s new B160, a 160mm (6.5 inch) cone driver with lightweight polymer diaphragm. This bass unit plus the new 19mm (0.75 inch) tweeter produced impressive volume levels, good bass extension and uncommon accuracy. C25 was a logical choice for music lovers assembling their first high-quality audio system.

C35 (1988-91)

C35 was a bookshelf two-way system using the new 200_19 format Uni-Q: incorporating a 200mm (8 inch) polymer cone bass/midrange unit with a 19mm (0.75 inch) fabric dome tweeter.
It is ironic that the sound of most bookshelf speakers changes when they are placed on their side, as so many bookshelves dictate. This is due to the speaker’s asymmetrical dispersion. Thanks to KEF’s new Uni-Q array the C35 achieves symmetrical dispersion both horizontally and vertically making it ideally suited to this application. In either orientation, the result is superior stereo sound throughout the listening room.

C55 (1988-91)

The C55 combined the type 200_19 Uni-Q array with a 200mm passive radiator in a compact two-way system with bass extension to 48Hz (-6dB). Mounted in matched die-cast housings, the passive radiator and Uni-Q array were covered by a clip on injection-moulded grille specially profiled to minimize ‘tunnel’ effects. Whilst small enough for bookshelf mounting, the C55 would perform equally well on dedicated stands. The symmetrical dispersion of the Uni-Q array means that mounting orientation, horizontal or vertical, is not critical to the sound – so the user has increased flexibility with installation.

C75 (1988-91)

In the C75 and 95 the Uni-Q array is a type 200_25 - comprising a 200mm (8inch) polymer cone midrange and a coincident mounted 25mm (1 inch) soft dome tweeter. In the C75 this is crossed over to a closed box loaded bass driver to create a floor-standing three way system where the traditional KEF clean and extended bass is matched to the uniform and symmetrical dispersion of the new Uni-Q array.

C95 (1988-91)

In the C75 and 95 the Uni-Q array is a type 200_25 - comprising a 200mm (8inch) polymer cone midrange and a coincident mounted 25mm (1 inch) soft dome tweeter. The woofer and tweeter not only share the same axis, but also have their acoustic centres in the same plane. And, as both units have similar directivity in the crossover region, you experience pin-point stereo imaging with reduced tonal colouration throughout a broader area of your listening room.
From the award winning Reference Model 104/2 the C95 inherits coupled cavity bass loading which allows the efficiency of a reflex system with the superior transient behaviour of a closed box. The addition of conjugate load matching provides the amplifier with a pure resistive load with subsequent benefits in ease of drive and in exploiting the full power output of the amplifier.

C200SW (1989-91)

The C200SW was a passive stereo subwoofer system designed specifically to operate with the C-Series models C15 and C25. Two matched enclosures derive their power for the existing amplifier – no additional amplification is required.
Combining the C200SW with either the C15 or C25 produces a full-range three-way system with bass response extending down to nearly 35Hz. As the C200SW relieves the C15 and C25 of the need to reproduce the lowest frequencies, the system’s overall dynamic capabilities are increased, with improved clarity and definition in the midrange.

C45 (1990-91)

In 1990, the C45 was added to the C-Series to strengthen and expand the range. It was a two-way closed box system with a 200mm (8inch) bass unit matched with the SP1260 metal dome tweeter.

C65 (1990-91)

In 1990, the C65 was added to the C-Series to strengthen and expand the range. Based on the C45 drivers and crossover it was a two-way passive radiator system with a 200mm (8inch) bass unit, 200 mm passive radiator, matched with the SP1260 metal dome tweeter.

C85 (1990-91)

In 1990, the C85 was added to the C-Series to strengthen and expand the range. It was a three-way ported system with a 200mm (8inch) bass driver and a type 200_25 Uni-Q array.
